Share 'So, I have a chance to interview Jason Newsted for my zine.'

The only issue I have with it is that I have to go through his agent to do this. I'm not sure how into it I am into it because of this. I want to ask things from his whole career and I think I am a=only supposed to ask questions about up and coming stuff.
Any suggestions?
And, what would you ask if you had this chance?
Topics and ideas please.
Thank you.
